That car expects premium. If you put low octane it will try to retart the spark sufficiently to avoid predetonation. Your power will suffer and the engine will run hot - hopefully not too hot or that will end all of this in a hurry.
The moral of the story is that 10 cents per gallon savings is not the saving you want or need.
Buy your gas at Costco and you will pay less for your premium -- probably less than a lot of regular stations.
